Hi, may I answer your health queries right now ? Please type your query here... My child is 3 and half years old . But he does not talk. He had been saying ma- baba when he was 7 months old but now he just says something in his own gurgling language. His hearing is also proper. He is very naughty and he is always doing something or the other . He never sits idle. We want to know why his speech is not developing.
